Although you don't hear it much since Opie & Anthony started doing the Free FM version of the show, Ennio Morricone's "Ecstasy of Gold" from the movie "The Good, The Bad, and the Ugly" was the old theme song tothe Opie & Anthony Show on XM 202 (that ran before the Rage Against the Machine "Street Fighting Man" clip), serving as an extended warm-up to the start of the show.
This is a great song, Opie & Anthony used it well in making it one of their signature songs, and it's too bad they no longer use it. This song has also been used by Metallica to start their concerts, and you can hear it starting their concert on one of their live albums.
